Characterization of obstacle negotiation behaviors in the cockroach, Blaberus discoidalis.
Within natural environments, animals must be able to respond to a wide range of obstacles in their path. Such responses require sensory information to facilitate appropriate and effective motor behaviors. The objective of this study was to characterize sensors involved in the complex control of obstacle negotiation behaviors in the cockroach Blaberus discoidalis. Previous studies suggest that a...
متن کاملControl of obstacle climbing in the cockroach , Blaberus discoidalis
An advantage of legged locomotion is the ability to climb over obstacles. We studied deathhead cockroaches as they climbed over plastic blocks in order to characterize the leg movements associated with climbing. Movements were recorded as animals surmounted 5.5-mm or 11-mm obstacles. The smaller obstacles were scaled with little change in running movements. The higher obstacles required altered...
متن کاملPurification of the pro-phenol oxidase enzyme from haemocytes of the cockroach Blaberus discoidalis.
Pro-phenol oxidase was purified from the haemocytes of the cockroach Blaberus discoidalis by Blue Sepharose chromatography, hydrophobic-interaction chromatography on a Phenyl-Superose column and, finally, gel filtration on a Superose 6 column. Results suggest that the molecule exists as a polymer of identical 76 kDa monomeric units. The enzyme is a glycoprotein with pI of 5.2 and can be convert...
متن کاملLeg kinematics and muscle activity during treadmill running in the cockroach , Blaberus discoidalis :
We have combined high-speed video motion analysis of leg movements with electromyogram (EMG) recordings from leg muscles in cockroaches running on a treadmill. The mesothoracic (T2) and metathoracic (T3) legs have dierent kinematics. While in each leg the coxa-femur (CF) joint moves in unison with the femurtibia (FT) joint, the relative joint excursions dier between T2 and T3 legs. In T3 legs...
متن کاملKinematic and behavioral evidence for a distinction between trotting and ambling gaits in the cockroach Blaberus discoidalis.
Earlier observations had suggested that cockroaches might show multiple patterns of leg coordination, or gaits, but these were not followed by detailed behavioral or kinematic measurements that would allow a definite conclusion. We measured the walking speeds of cockroaches exploring a large arena and found that the body movements tended to cluster at one of two preferred speeds, either very sl...
